4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulation and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Check that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the holes.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.
To check the GPS reception status, follow the procedure below:
Position the vehicle in an open area
Wait for 15 minutes with the ignition on

Fault finding - Functions
General operation
The NAV 4R system includes the following functions:
●CD multi-changer (according to options).
●Satellite guidance navigation.
●Display (according to options).
●External thermometer.
●Clock.
●Audio.
●Seat belt warning light (Laguna II only).
1 - CD multi-changer
The CD multi-changer located on the dashboard can hold up to 6 CDs. Audio CDs and CDs recorded by the
customer may be played.
The CD changer does not play MP3 CDs.
2 - Navigation
This function guides the driver by displaying maps and issuing voice messages. The addresses for guidance are
entered using the keypad.
3 - Display
The display is used to show information such as navigation maps, radio, CD title (MP3 CDs optional), time,
temperature, etc.
4 - Thermometer
The 4R central communication unit may display the exterior temperature via:
–the UCH (only on Mégane and Scénic II phase 2),
–the sensor located on the right-hand door mirror (other vehicles).
The temperature is also transmitted to the climate control computer. This parameter can be viewed using parameter
PR006 External temperature.
5 - Clock
This function allows the time to be displayed on the video screen.
6 - Audio
Two audio systems are available:
–Standard 4X15 W,
–Cabasse 4X40 W.
These systems enable the user to listen to AM/FM radio, CDs (MP3 CDs optional with the Cabasse system) and
satellite navigation voice messages.
7 - Seat belt warning light (Only on Laguna II phase 2).
Seat belt warning light lit on the display.
